Description

[Detailed description of the invention] [Industrial application field] This invention is a graft support that is attached to the joint between rootstock and scion when grafting various fruit vegetables such as tomatoes, eggplants, and cucumbers. It's about the ingredients.

[Conventional technology]

Conventionally known methods of grafting include, for example, as in Utility Model Publication No. 48-45299, in which slanted cuts made on the rootstock and scion are joined to each other, and the outer periphery of this joint is washed. There is a method of clamping and fixing with clips such as scissors, or a method of fixing and holding by wrapping the joint part with a lead plate that can be bent freely and maintains its shape.

In addition to the above-mentioned support means such as clips and lead plates, there are
As in No. 31487, a power factor increasing ring is provided in the middle part of a synthetic resin cylindrical body with a vertical opening in the length direction, and a pair of rings protruding from the outer peripheral surface of this ring are provided. There is also known a support device having a structure in which a vertical line-shaped opening is opened by pinching the opening/closing projection, and the joint portion is sandwiched between the cylindrical bodies.

Furthermore, when using a cylindrical body made of synthetic resin, an S-shaped notch is provided in the length direction of a silicone tube with both ends cut horizontally, and this notch is opened to join the joint part with the tube. Something like PHYSIOLOGIA PLANTARUM
72:153159P 1988.

[Problems that ideas should solve]

Among the various supports mentioned above, the method of holding each cut end with clips not only puts a burden on the young seedlings due to the weight of the clips, but also
The problem is that the clamping pressure that presses the outer peripheral surface of the joint is always constant, which hinders the growth of the stem.
Even when the stem has grown and the joint surface has taken root,
Since the clips do not fall naturally from the stem and remain attached, each clip must be removed from the stem at a predetermined time, making management troublesome.

In addition, the method of wrapping the lead plate is similar to the case of clips, as the weight of the lead puts a strain on the stem.
The problem is that this lead plate does not fall off naturally even after the stems have grown, requiring removal work.

Furthermore, among those made of synthetic resin cylindrical bodies,
As in Utility Model Publication No. 48-31487, a power factor increasing ring is provided in the middle of the tube, and by pinching a pair of opening/closing protrusions protruding from the outer circumferential surface of this ring,
A support device in which the cylindrical body opens and closes, as in the case of the above-mentioned clip, has a power factor increasing ring that presses the stem from the outer circumferential surface even when the stem grows and the joint surface becomes attached. Therefore, there is a problem in that the tubes must remain attached without falling off the stem by themselves, and each tube must be finally removed from the stem at a predetermined time.

On the other hand, supports that have only an S-shaped cut in the length direction, such as the silicone tube described above, are lightweight and do not add weight to the stem because they are made of a simple cylindrical body called the tube. It does not cause any stress, and after this tube is attached to the cut end of the graft, the joint surface of each cut end takes root and becomes thicker as the stem grows.
This has the advantage that the cut along the length of the tube is pushed open from the inside and the tube automatically falls off the stem, so there is no need to take the trouble to remove it afterwards, as with the above-mentioned clip. have.

However, this tube-shaped support has a means for opening the S-shaped notch on the outer peripheral surface of the tube, that is, a ring for increasing the power factor in the tube-shaped support of Utility Model Publication No. 48-31487. , there is no means for opening the notches provided in the length direction of the cylindrical body. Therefore, the operating method for attaching this tube to the joint of the cut ends of the rootstock and scion is to firmly join the joints of the cut ends of the rootstock and scion with both hands, and then connect this joint with the thumb and index finger of your left hand. Then, using the thumb and forefinger of the right hand, open the S-shaped notch in the tube and wrap it around the inside of the tube so that the rootstock and scion join together. The disadvantage is that the operation of attaching the tube to the section is troublesome and takes time.

On the other hand, in the case of this tube-shaped support, in addition to the installation method described above, a simpler and more efficient method is to open the S-shaped notch in the tube and join. Without wrapping the bottom end of the tube around the rootstock, insert the bottom end of the tube directly into the cut end of the rootstock until the cut end is located in the middle of the tube, and then insert the bottom end of the tube into the opening at the top end of the tube. One possible method is to insert the cut end of the scion into the section.

However, when attaching the silicone tube to the joint using this insertion method, when the lower end of the tube is fitted into the cut end of the rootstock, the cut end of the rootstock is hidden by the center of the tube and cannot be seen. Moreover, if both ends of the tube are cut horizontally like this tube, it is impossible to tell from the outside which direction the sloped surface of the cut end of the rootstock hidden inside the tube is facing. . If it is not possible to determine which direction the sloped surface of the cut end of the rootstock located inside the tube faces, then when inserting the cut end of the scion into the tube, the sloped surface of the cut end of the scion I don't know what direction to insert it into the tube.

Therefore, with a tube that has horizontal cuts at both ends, it is not possible to use the easy-to-operate insertion method described above, and it is difficult to open the S-shaped cut in the tube and wrap it around the joint of the graft. This has the problem that a winding method must be used.

[Means to solve the problem]

The present invention is based on the above-mentioned graft supports.
The object of the present invention is to provide a grafting support that is easy to handle, accurate, and efficiently performs grafting work by improving the disadvantages of the tube-shaped support while taking advantage of its advantages.

As a specific means for this purpose, the present invention uses a synthetic resin elastic material having a diameter large enough to elastically hold the outer periphery of the graft joint over almost the entire circumference, and having a notch extending from one end to the other end. In a graft support made of a cylindrical body, at least the upper end surface of both upper and lower end surfaces of the elastic cylindrical body is an inclined cut surface corresponding to the slope of the cut end of the graft with respect to the axis of the cylindrical body. [Function] The graft support according to the present invention is characterized by:
When attaching the lower end of the cylindrical body to the cut end of the rootstock, the inclined cut surface at the upper end of the cylindrical body is aligned in the same direction as the inclined surface of the cut end of the rootstock. The cut end of the rootstock is fitted into the cut end, and the cut end of the rootstock is positioned at the middle part of the cylindrical body. When the cylindrical body is attached to the rootstock in this way, the sloped cut surface at the upper end of the cylindrical body replaces the sloped surface of the cut end of the rootstock that is shielded inside the cylindrical body, The direction will be displayed externally. As a result, when inserting the cut end of the scion into the upper end of the cylindrical body,
When inserting the scion in such a manner that the sloped surface of the cut end matches the slope direction of the sloped cut surface at the upper end of the cylindrical body, the cut end of the scion and the cut end of the rootstock are inserted into the cylindrical body. In this case, the two cut ends can be joined in a simple and efficient manner.

Further, in the cylindrical body support of this invention, since the end of the cylindrical body is formed into an inclined cut surface, the opening area of the cut end on this sloped cut surface can be substantially enlarged. As a result, at least when an inclined cut surface is provided at the upper end of the cylindrical body, when inserting the cut end of the scion into the upper end of the cylindrical body, the cut end of the scion is inserted into the upper end of the cylindrical body. It is extremely easy to insert into a large slanted cut surface.

For the same reason, if the inclined cut surface is provided not only at the upper end of the cylindrical body but also at the lower end, when the cylindrical body is attached to the cut end of the rootstock, The cut end formed by the inclined cut surface at the lower end can be easily inserted. Therefore, in this cylindrical body support tool, the lower end of the cylindrical body is directly fitted into the cut end of the rootstock, and the cut end of the scion is inserted into the upper end of this fitted cylindrical body. Grafting operations using the insertion method can be performed extremely easily.

〔Example〕

Next, an embodiment of the graft support of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the shape of this support, and this graft support is made of a rootstock as shown in FIG. It is formed of a cylindrical body 20 made of a lightweight and elastic material such as rubber or synthetic resin, which is fitted across the joint 3 of the scion 2.

This cylindrical body 20 has a diameter D to such an extent that the hollow portion 21 elastically holds the outer periphery of the joint 3 between the rootstock 1 and the scion 2 over almost the entire circumference by a predetermined flesh pressure. The joint portion 3 is formed in the portion 21 so as to be elastically held under pressure from the outer periphery.

Further, at least one end of this cylindrical body 20, preferably both upper and lower ends, are provided with inclined cut surfaces 23 and 24 in directions corresponding to the inclined cuts 4 of the rootstock 1 and the inclined cuts 5 of the scion 2. There is. The inclined cut surfaces 23 and 24 in this cylindrical body 20 are
This is to suggest the direction of the sloped surfaces of the sloped cuts 4 and 5 in the rootstock 1 and the scion 2,
Slanted cuts 4, 5 of rootstock 1 and scion 2 are not necessarily required.
It does not have to be parallel in a strict sense to the inclined plane of.

Further, the cylindrical body 20 is provided with a notch 22 that reaches from one end to the other end. This cut 22 does not apply unnecessary pinching pressure to the outer circumferential surface of the stem after the graft joint 3 has taken root, and allows the stem to expand easily as the stem diameter increases as it grows, as shown in FIG. This is to allow the stem to automatically fall out of the stem when it opens and the stem diameter further increases. Therefore, the notch 22 may be cut away from the beginning along the entire length of the cylindrical body 20, but it may be formed in a thin wall shape or perforation shape, and as the stem grows. It may be one that is automatically separated or one that is separated as necessary during work.

The cut 22 may be provided at any location, but in this embodiment, the cut 22 is provided at the intermediate portions 25 and 26 of the inclined cut surfaces 23 and 24 at both the upper and lower ends of the cylindrical body 20. It is being

Further, the outer peripheral surface of the cylindrical body 20 is provided with a large number of uneven surfaces 27 along the length direction. This uneven surface 27 functions as a non-slip to facilitate workability during installation, but it not only functions as a non-slip, but also prevents the scion from slipping when the scion is inserted into the upper end of the cylindrical body. It also has an advantage in terms of reinforcing the strength of the shaped body.

That is, as described above, the slanted cut surfaces 23, 2 are provided at least at the upper end or both upper and lower ends of the cylindrical body 20.
4, the opening area of the cut end of this inclined cut surface increases. Therefore, the insertion operation when fitting the lower end of the cylindrical body 20 to the cut end 4 of the rootstock 1 and the upper end of the cylindrical body 20 are performed. It is possible to facilitate the insertion operation when inserting the cut end 5 of the tree 2.
The fact that the insertion operation is easy due to the large cut surfaces of the inclined cut surfaces 23 and 24 means that the outer diameter of the rootstock 1 and the scion 2 is smaller than that of the cylindrical body 2.
Even if the inner diameter of the cylindrical body 20 is slightly larger than that of the cylindrical body 20, the cylindrical body 20 has the advantage that it can be appropriately fitted inside the cylindrical body 20. Moreover, the fact that the insertion operation is easy has the advantage that a flexible material that is not very hard can be selected as the cylindrical body 20. Furthermore, in the case where the cylindrical body 20 is soft, when the grafting work is completed and the rootstock 1 and the scion 2 are established, the notch 22 provided in the length direction of the cylindrical body 20 expands. do,
It is also suitable for the condition of automatically making it easier to fall.

However, if the cylindrical body 20 is soft, even if there is no problem in fitting the cylindrical body 20 into the cut end 4 of the rootstock 1, the upper end of this cylindrical body 20 is When inserting the cut 5 of 2,
A problem arises in that the cylindrical body 20 is bent due to the weight of the scion 2. To solve this problem, if a large number of uneven surfaces 27 are provided along the length direction on the outer peripheral surface of the cylindrical body 20, the uneven surfaces 27 will strengthen the strength of the cylindrical body 20. Therefore, even if the cylindrical body is flexible to some extent, the cylindrical body 20 can be appropriately supported without being bent when the scion is inserted.

Furthermore, the provision of this uneven surface 27 also provides conditions for easy expansion of the notch 22 provided in the length direction of the cylindrical body 20 when the cut 22 expands at a predetermined time and falls. Are suitable.

Next, to explain the case where the above-mentioned cylindrical body 20 is used to support the joint 3 of a graft, as shown in FIG. The rootstock 1 is inserted in the same direction as the slanted cut 4 of the tree 1 until the slanted cut 4 of the rootstock 1 is placed in the middle part of the cylindrical body 20.

When inserting this cylindrical body 20 into the cut end 4 of the rootstock 1, the cylindrical body 20 is basically inserted as described above.
It is sufficient to insert the inclined cut surface 23 at the upper end in the same direction as the inclined cut surface 4 of the rootstock 1, but as in the embodiment shown in FIG. Slanted cut surfaces 23, 24
is provided, the cylindrical body 20 is attached to the rootstock 1
When inserting into the cut 4 of the cylindrical body 20, the inclined cut surface 24 of the lower end and the inclined cut 4 of the rootstock 1 can be contrasted at a very close position, so that the inclined surface of the cylindrical body 20 and the cut 4 of the rootstock 1 can be compared. It is suitable for attaching the cylindrical body 20 at an accurate position by making it easy to judge the correspondence with the inclined surface.

In this way, the cylindrical body 20 is attached to the cut end 4 of the rootstock 1.
When the cylindrical body 20 is attached to the cylindrical body 20, the slanted cut surface 23 at the upper end of the cylindrical body 20 replaces the cut surface 4 of the rootstock 1, which is difficult to discern from the outside and is shielded inside the cylindrical body 20, by cutting the slanted cut surface 23 at the upper end of the cylindrical body 20. This means that the direction of the image is displayed externally. In other words, the upper end inclined cut surface 23 of the cylindrical body 20 provides a guideline as to the direction in which the inclined surface of the cut end 5 of the scion 2 should be inserted into the cylindrical body 20. .

As a result, when inserting the cut end 5 of the scion 2 into the cylindrical body 20, as shown in FIG. It is only necessary to insert the scion into the cylindrical body 20 so as to match the direction of the inclined cut surface 23. When inserted in this way, the inclined cut end 5 of the scion 2 will be
As shown in FIG. 2, inside the cylindrical body 20, the inclined cut 4 of the rootstock 1 is automatically closely fitted in the correct position, and in this state, the work of joining both the cuts 4 and 5 is completed.

[Effect of idea]

As described above, the graft support according to the present invention has, at least at the upper end of the tube-like body, preferably at both the upper and lower ends, an inclined cut surface corresponding to the cut ends of the rootstock and scion forming the graft. Therefore, when inserting the lower end of the cylindrical body into the cut end of the rootstock, the direction of the inclined cut surface at the upper end of the cylindrical body is
By inserting the rootstock according to the direction of the sloped surface of the cut end of the rootstock, even if the direction of the sloped surface of the cut end of the rootstock is hidden inside the cylindrical body and cannot be seen from the outside, the sloped cut surface at the upper end of the cylindrical body can be inserted. , the direction of the sloped surface of the cut end of the rootstock hidden inside will be displayed instead, so in the first step of the installation operation of the cylindrical body, it is necessary to insert the cylindrical body at the exact position of the cut end of the rootstock. can be worn.

In the second step of inserting the cut end of the scion into the cylindrical body, which is the next operation, the cut end of the scion is placed in a state where the direction of the inclined surface matches the direction of the inclined cut surface at the upper end of the cylindrical body. The cut end of the rootstock and the cut end of the scion can be automatically matched correctly in the tube by simply inserting the tube into the tube. The second step of inserting the device into the body can be performed continuously and efficiently within an extremely short period of time.

Furthermore, by forming the end of the cylindrical body with an inclined cut surface, the opening area of the cut on the slanted cut surface of the cylindrical body can be substantially increased, so that the cylindrical body can be attached to the cut surface of the rootstock. When inserting the lower end of the cylindrical body into the cut end of the rootstock, when inserting the cut end of the scion into the upper end of the cylindrical body, the cut end of the scion can be easily inserted into the cut end of the cylindrical body. It can be easily inserted into the cut by the slanted cut surface, and therefore, the grafting operation can be easily performed by the insertion method through the cylindrical body. By accurately joining the rootstock and scion using the shaped body, a grafting effect with a good rooting rate can be expected.
